This is very cool,
clemburg. ++ for that. I was going to comment about cperl-mode, but I didn't know how to automate the process. Thanks!
Just for the sake of completeness, be aware that cperl sometimes breaks with funky perl code such as regexes, here documents, unusual quoting and things like that. But other than that it's an excellent way of doing it.
For printing Perl code, I usually use xemacs' "pretty-print" option, which is loaded with some package I can't remember right now. I don't know how to invoke it in batch mode though - you have to manually load the file and select the option from the menu. Pretty-print generates postscript according to your current font-lock settings, so you get colors (shading in a b/w printer), bold, etc.
